Applying
Lean to global logistics . . . a tutorial
by
Bob Masterson
As
United States manufacturers continue to compete in the global market,
logistics competency will be increasingly viewed as a competitive
differentiator. What follows is a guide to applying Lean principles to
a global logistics process.
What's
in this for you? Here are examples of waste discovered in the global
logistics processes of United States manufacturers. To make this
relevant to you, ignore the dollars and apply the percentages against
your business.
•
$324,000 (87 percent reduction) in courier expense (replaced paper
documents with self-service, Web-access electronic documents)
• 7,250 hours (50 percent reduction)
in customer service time (eliminated reactive communication and
replaced it with just-in-time communication)
• 7,596 hours (52 percent reduction)
in document preparation time (built a single database and automated
output)
• $739,000 (28 percent reduction)
in in-transit inventory cost (implemented communication with
customers, daily track and trace, made carriers responsible for
on-time deliveries, applied statistical measurements, eliminated
safety stock and fear factor)
• 17 days (36 percent reduction)
in throughput time
• 40 percent of logistics process steps (non-added-value)
• 60 percent of handoffs
• two days (66 percent reduction)
in air in-transit time (eliminated routine stop-off at forwarder at
origin and destination)
• 43 minutes (76 percent reduction) invested in each order
Applying
Lean to your global logistics process will:
• Improve service to your customer (lower cost, better communication,
greater reliability).
• Increase productivity of your operations by 20 to 100 percent
(remove waste, improve flow).
• Increase throughput by 20 to 100 percent.
• Decrease in-transit inventory by 10 to 50 percent.
• Improve cash flow.
• Measure carrier, forwarder and your process performance (add 20 key
performance measures).
• Increase profitability.
The
aim of Lean global logistics is the same as the aim of Lean manufacturing: deliver the right goods or service at the right time,
place and price, and with perfect quality. This is accomplished by
improving flow.
The
following 10 steps will guide you in improving the flow of your global
logistics process.
1.
Set expectations
Commitment
from the top management:
Lean will not work without a well-communicated, long-term commitment
from top management.
Involvement of operational-level,
cross-functional employees: Whether it's discovery, process writing,
value stream mapping, kaizens or celebrations, the people involved
should be from a variety of job functions. This
improves communication, knowledge and understanding, and ultimately
makes you more successful at Lean.
Give
employees tools, a voice, permission to improve their workplace:
Good employees want to improve their workplace and become more
productive; applying Lean gives them opportunities to do this.
2.
Discovery
The
purpose of discovery is to uncover the details of a process. Most
logistics processes really are not processes; rather, they are many
disjointed, random activities within company departments. These random
activities include no standard of service for customers, forwarders or
carriers. There is most often no standard documentation flow, no
statistical tools for management, no global reports, no comprehensive
plans to take advantage of technologies and, worst of all, no system
of continuous improvement.
This
often consists of asking more than 130 questions, depending on air,
ocean, import, export, foreign to domestic, and seeks to establish the
lowest levels of a process.
3.
Document process
Remember,
in global logistics we don't have cells or a shop floor, so there is
not that type of visibility. The process document is what we all see.
The
first process document is created from the results of discovery,
written out step-by-step, in clear detail. Each step is defined.
Timing, sequence and responsibility are assigned.
Everyone
in the process (shipper, carrier, forwarder, consignee, etc.) uses the
same process document.
The
process document provides shipper, consignee, forwarder and carriers
visibility and standard work.
4.
"Current state" value stream map
What
is your value stream? It might begin in Bangkok with a purchase order
being sent to Wisconsin, involves a factory in Wisconsin, a truck
between Wisconsin and Chicago, railroad between Chicago and Los
Angeles, stevedores in Los Angeles, a cargo vessel between Los Angeles
and Bangkok, customs in Thailand, a truck in Bangkok and a warehouse.
Each step requires communication and paperwork. Our value stream looks
a little bit different than a manufacturer. It includes physical
movement, communication and documentation.
Identify
every step in the process as value-added, non-value-added or
"non-value-added but necessary." To determine if a step adds
value, ask yourself, "Is the customer willing to pay for
this?"
"Non-value-added
but necessary" examples include compliance and hazardous materials
management. Measure
every step (i.e. operator's time, machine time). Identify
manual communication (paper, fax, voice) vs. electronic communication
(paperless). Identify
timelines (e.g. manufacturer's lead time, order to shipment time,
order to invoice, order to cash, time spanned, time invested). If you're not familiar with value stream mapping, pick up a copy of the
book "Seeing the Whole" by Dan Jones and Jim Womack.
Look
for Lean tools that will enable your work: standard work, statistics,
communication, poka-yoke, rework, setup time, rapid improvement, push
vs. pull, time observation, transactional waste, 5-S, spaghetti
diagram, flow diagram, visual management, employee involvement, theory
of constraints, kanban, leveling, takt time and others.
5.
"Future state" value stream map
This
is fun! It is a shared vision of what the value stream could look like
if it was created by the people who own it.
Having
identified non-value-added steps in the current state process, now
create a new map without those steps.
Look
at the times recorded in the current state and figure out how to
reduce them in the future state.
The
future state gives people the opportunity to be creative and to
challenge one another. It allows people to ask questions (What if?
Could we? Does this make sense? Is this really value-added? Would this
cost less?)
6.
Kaizen list
A
kaizen is a small, incremental improvement made by the people doing
the work.
This
kaizen list primarily represents the gaps between the current and
future state value stream maps.
Other
opportunities can also be included on the kaizen list (e.g. ideas,
things gone wrong, variations).
Publish
a kaizen newspaper and communicate current kaizens, open kaizens,
percentage completed, waste eliminated and money saved.
7.
Sustained
Kaizen
event are not complete until proven sustained. Sometimes
kaizens can be proved sustained immediately. Sometimes they have to be
proved over weeks or months.
8.
Update process document
Once
proved sustained, update the process document, communicate changes to
everyone involved and send them a revised process
document.
9.
Tie to corporate objectives
Every
process improvement must be quantifiable. Whether it is service,
dollars, hours or productivity, it must be quantified and then tied to
the corporate objective.
Examples
of corporate objectives are improve profitability, improve return on
net assets and improve cash flow.
10.
Celebrate
Recognize
and celebrate achievement as often you can! Look for reasons to
celebrate! Parties, lunches, bonuses, T-shirts . . . the list goes on
and on. Somehow recognize the achievement of the kaizen members.
Once
you have finished celebrating, pick another kaizen, get a
cross-functional team together and figure out how to improve!
You
can continue to cope or continue to improve. The choice is yours.
